Dr Kurt HaasPrimary Investigator
In the Haas Lab we directly image neuron growth within the intact and awake embryonic brain. We image both rapid growth dynamics over seconds to minutes, and long term changes over days, to investigate mechanisms underlying normal and abnormal neuronal development. |

Warren MeyersLab Technician
Warren joined the lab in 2016 after completing his Master's degree under Dr. Geoffrey Hammond at UBC. As a specialist in biochemistry and cell biology, his main role in the Haas Lab is to develop high throughput tools and cell line-based screening platforms to characterize gene variants associated with autism spectrum disorder (ASD). Warren is also part of our core team involved in the selection and prioritization of ASD-associated gene variants for the Pacific Autism Research Group. 604-827-5840 (lab) |

Wun Chey SinResearch Associate
WC Sin did her postdoctoral training at the Institute of Molecular & Cell Biology in Singapore and at the Cold Spring Harbor Laboratory in New York. She spent a few years in a New York biotechnology company that specializes in cancer gene discovery before continuing her research at UBC, focusing on the role of inflammation in brain cancer development. She is involved in the functional characterization of autism associated gene variants in the lab since October 2017. |

Tristan Dellazizzo TothDoctoral Student
Tristan investigates how growing neurons in developing vertebrate brains integrate synaptic input and encode information in an action potential output, and how these integration and encoding properties change with experience across the entire dendritic arbor. To be able to record the different patterns of activity across the entire 3D space of neuron, he employs a verity of genetically encoded biosensors and images individual neurons in Xenopus tadpoles in vivo using a custom built acousto-optics based random-access two-photon laser-scanning microscope system. |

Peter HoggDoctoral Student
Peter uses Xenopus laevis tadpoles to study early neuronal development, dendritic arborization, and synaptogenesis. His experimental work makes use of in vivo two-photon imaging to collect structural data of single neurons during development, as well as population calcium dynamics. Peter has an interest in the application of bioimage analysis and machine learning to investigate neuronal development. |

Sina SafabakhshLab Technician
Sina works on two major projects. The first project is to study the effects of Early-Life Seizures (ELSs) on the developing brain, which largely involves immunohistochemistry, 2-photon and confocal imaging, and associated analysis. The second project is a high-throughput study of the effects of genetic mutations associated with Autism Spectrum Disorders (ASDs) on protein structure and function. This project involves the growth, maintenance, and genetic manipulation of large-scale cell culture assays. |

Alessandro CauLab Technician
Alessandro joined the lab as an undergraduate in 2015 and went on to receive his Bachelor of Science degree following the completion of his Honours Thesis in 2017. For his thesis, he investigated the effects of Autism Spectrum Disorder (ASD)-associated gene variants on activity-dependent neuronal growth in Xenopus laevis tadpoles. Currently, Alessandro is involved in a few different projects that include conducting high-throughput assays to test ASD-associated gene variants as well as studying the effects of early life seizures on synaptogenesis and synaptic plasticity in the developing brain. |

Patrick ColemanMasters Student
Pat works on Image and Signal processing techniques for the collection and analysis of in-vivo neuronal signals. His work allows analysis of 5D signal across an entire dendritic arbors, combining 3D morphology with structural changes over time, as well as fluorescent indicator responses to stimuli. This helps in understanding dendritic informational processing, by establishing links between the structural and functional changes. |

Fabian Meili, MScLab Technician, Lab Manager
Fabian joined the lab in early 2016 as both Lab Manager and Research Technician. He was tasked with creating several hundred constructs of ASD Gene Variants in a variety of expression clones for UBC's ASD collaboration, as well as various cloning projects for the Haas Lab. He is designing and performing all of the flow cytometry-based high-throughput screening for various functional and biochemical features of ASD-associated gene variants. As Lab Manager, he is also in charge of everything related to lab safety and new Haas Lab member orientations, as well as teaching new Undergraduates joining the lab to learn molecular biology techniques.

Dong Hwan Kim (DK)Doctoral Student
DK is currently a PhD student in the Haas Lab. DK is investigating how seizures alter dendritogenesis and synaptogenesis by directly imaging developing neurons during experimentally induced seizures within the intact and awake brain. |

Dr Janaina BruscoPostDoctoral Fellow, Former Member
Jana investigates molecular pathways for synaptic plasticity and metaplasticity during brain development. Jana uses a broad range of molecular and imaging techniques to show that mitochondria are not just important for energy production, but are key organelles that control the availability of synaptic proteins at post-synaptic terminals, thus modulating plasticity (Brusco and Haas, 2015) |

Kathryn PostDoctoral Student
Kathryn investigates Autism Spectrum Disorder (ASD) associated genes and gene variants. Specifically she is interested in the effect of ASD-associated variants on dendritogenesis in young, developing neurons. Using two-photon microscopy she investigates the development of phase 2 and 3 optic tectal neurons expressing ASD-gene variants. She is also interested in functionally characterizing all identified gene variants using genetic interactions determined through Synthetic Dosage Lethality (SDL) screens in Saccharomyces cerevisiae. |
